Active Galactic Nuclei (AGN)

AGN is a catch-all term for most types of galaxies that have extremely bright and concentrated emission from their central regions. This light is believed to come from matter in the form of gas, dust, and even whole stars being sucked into the central black hole. As all of this material spirals in, it gets very hot and very bright, much brighter than the stars and other luminous material in the center of the galaxy.
